FIELD: physics.
SUBSTANCE: device is related to radio engineering and may find application in receiving devices. The device containing serially connected amplifier of intermediate frequency, coupler, multiplication unit, the second outlet of which is connected with the second outlet of coupler, band filter of low frequencies, amplifier, also includes the following serially connected components, i. e. analogue-digital converter (ADC), programmed logical integral circuit (PLIC) and electronic key, as well as a downward limiter and digital-analogue converter. Output of downward limiter is connected to input of intermediate frequency amplifier, output of amplifier is connected to ADC input and second input of electronic key, the output of which represents a device output, the second output of PLIC is connected with DAC input, the output of which is connected with second input of downward limiter, the first input of which represents a device input.
EFFECT: increased efficiency of noises suppression.
